A Manhattan elementary school teacher was arrested Tuesday night for assaulting a second-grader, cops said.

Osman Couey, 53, was busted after allegedly throwing 7-year-old Ka’veon Wilson across a hallway last December, according to police. The incident was caught on video.

Couey has been teaching at PS 194 in Manhattan since 1993, and has a history of four letters of reprimand on his record, according to the Department of Education.

Couey is charged with assault and acting in a manner injurious to a child under 16.

“I don’t trust this school,” said Wilson’s mother, Chantel Phinazee, in an interview with ABC. “Y’all waited a month to tell me, didn’t care at all about what was going on with my son. You kept it from me. So I don’t trust them no more than I did before.”

Couey was reprimanded, but not removed, in 2013 for allegedly throwing a special needs student, Xavier Gomez, 7, down a flight of stairs.

Before Couey was arrested, the Department of Education tried to address parents’ concerns in a brief statement:

“This behavior is deeply troubling, and we are seeking to terminate this teacher’s employment. He has been removed from the classroom and reassigned away from students.”
